Description

  The present invention relates to a car wash machine that is installed, for example, in a gas station and used for car washing.

An example of the conventional car wash machine is disclosed in Patent Document 1.
The car wash machine disclosed in Patent Document 1 performs a car wash operation (washing, drying, waxing, etc.) on a vehicle to be washed that is stopped at a predetermined position while the car washing machine body travels in the front-rear direction. A washing section comprising a plurality of brush devices for cleaning the front and rear surfaces, the top surface, and the side surfaces of the vehicle to be cleaned, and a water spray nozzle for spraying cleaning water to the vehicle to be cleaned. , A drying unit comprising a plurality of blower nozzles for drying the upper surface and side surfaces of the vehicle to be cleaned, and water droplets scattered from the brush device and the watering nozzle located behind the cleaning unit and in front of the drying unit to the drying unit having the blower nozzle And a shutter body that cuts off so as not to reach.

  Chains are integrally fixed to both side edges of the shutter body, and these chains are engaged with sprockets provided in front and rear, respectively, above the car wash machine body. Sprockets provided on both sides of the rear are connected by a shaft, and a gear motor that rotationally drives the shaft is provided. By rotating the gear motor, the shutter body is moved up and down via the shaft and the sprocket. The shutter body has a structure in which elongated steel plates arranged in the width direction of the car wash machine main body are vertically connected, and has at least rigidity that does not bend against blowing from the blower nozzle or strong winds in stormy weather. Yes. In addition, sensor boxes containing photoelectric switches are attached to the lower end portions on both sides of the shutter body so as to face each other.

  Based on the above configuration, when cleaning the vehicle to be cleaned, the shutter body lowered from the standby position to the lower limit position detects the vehicle to be cleaned by the photoelectric switch of the sensor box. It is lifted and lowered without contact with the vehicle to be cleaned along the shape.

  As a result, the shutter body is moved up and down, so that cleaning water or the like is not scattered from the cleaning unit to the drying unit, and air blown from the drying unit is blown into the cleaning unit to adversely affect the cleaning of the vehicle to be cleaned. Therefore, it is possible to perform a quick car wash in which washing and drying can be performed simultaneously before and after the shutter body, and there is no need to separate the washing unit and the drying unit, so the size of the car washing machine can be reduced. It becomes possible.

  In addition, the car wash machine disclosed in Patent Document 2 is provided with a movable curtain that is extended to a support roller that is rotationally driven by a prime mover through a transmission mechanism, and is suspended so as to be retracted. A vehicle body detection limit switch is fixed to the vehicle body, and a ring-shaped non-directional contact is provided on the vehicle body detection limit switch.

  Further, a limit switch for raising and lowering the movable curtain is fixed in parallel on the lower edge of the movable curtain, and upper and lower limit dogs at which the above limit switches are operated are arranged on the upper and lower surfaces of the traveling frame. When these limit switches are operated, the rotation of the prime mover is stopped and the upper limit and lower limit positions of the movable curtain can be regulated.

  In this configuration, the to-be-washed vehicle is detected by the above-described touch sensor (body detection limit switch) being directly in contact with the top surface of the to-be-washed vehicle, and the touch is repeatedly contacted and detached from the to-be-washed vehicle, The raising and lowering of the movable curtain is controlled.

This allows the lower edge of the movable curtain to be always close to the upper surface of the vehicle to be cleaned, especially when cleaning the trunk or bonnet of the vehicle to be cleaned, where the cleaning water is likely to splash outside the car washer. Water can be prevented from splashing outside.

It is necessary to provide a gap with sufficient margin between the lower end of the shutter body and the upper surface of the vehicle to be cleaned, and water splashes from this gap should not be scattered to some extent from the cleaning section to the drying section. There was a problem that it was not possible.

  Further, according to the configuration of Patent Document 2, since the limit switch for detecting the vehicle body repeatedly contacts and separates from the vehicle to be cleaned in order to control the up and down movement of the movable curtain, there is a problem that a trace remains on the vehicle to be cleaned. There is.

  In addition, it is necessary to provide a sensor box composed of photoelectric switches, or a vehicle body detection limit switch and a touch sensor as a sensor for raising and lowering the shutter body or the movable curtain, and as a safety mechanism.

  In addition, when a photoelectric switch is provided at a position where water splashes such as the lower end of the shutter body, in order to avoid erroneous detection of the photoelectric switch due to water splash, the watering nozzle and the sensor box are spaced at a predetermined interval (water splashes to some extent). There is a problem that a space for separation is necessary, and the main body of the car wash machine increases in size to provide this space.

  Then, an object of this invention is to provide the car wash machine which can improve the scattering of a water droplet from the washing | cleaning part to a drying part, or can reduce a car wash machine main body without incurring manufacturing cost.
